The purpose of this study was to analyze residential segregation in the city of Tunja, Colombia, through the use of spatial statistics and Geographic Information Technologies. It establishes the scale and pattern of segregation from traditional indexes, calculated through the program GeoSegregation Analyzer; And the mapping of the distribution of 11 socioeconomic groups at the census tract level with the ArcGIS 10.1 program. This study allowed to establish that the city exhibits a middle segregation and a pattern of spatial distribution similar to the present one in other cities of Latin America. The analysis of traditional indexes and the spatialization of socioeconomic variables provide a panoramic view of residential segregation and should therefore be understood as a basis for deeper studies involving other dimensions of the phenomenon.
